(1328+3×)-728=1500 , 744+(4×-544)=1400 , (7325-2×)-409=4178 , 9907-(8×+325)=4214​

Answer 1

Ответ:

Пошаговое объяснение:

1328+3х=2228. 744+(4х-544)=1400

3х=2228-1328. 4х-544=656

3х=900. 4х=656+544

х=900:3. 4х=1200

х=300. х=1200:4

х=300

(7325-2х)-409=4178. 9907-.

( 8х+325)=4214

7325-2х=4587. 8х+325=5693

2х=7325-4587. 8х=5693-325

2х=2738. 8х=5368

х=2738:2. х=5368:8

х=1369. х=671

Answer 2

Let's solve each of these equations step by step:

1. $1328 + 3x - 728 = 1500$

   First, combine like terms on the left side of the equation:

   $1328 - 728 + 3x = 1500$

   $600 + 3x = 1500$

   Next, isolate the variable $x$ by subtracting 600 from both sides:

   $3x = 1500 - 600$

   $3x = 900$

   Now, divide both sides by 3 to find $x$:

   $x = 900 / 3$

   $x = 300$

   So, the solution to this equation is $x = 300$.

2. $744 + (4x - 544) = 1400$

   First, distribute the 4 on the left side of the equation:

   $744 + 4x - 544 = 1400$

   Next, combine like terms on the left side:

   $744 - 544 + 4x = 1400$

   $200 + 4x = 1400$

   Now, isolate $x$ by subtracting 200 from both sides:

   $4x = 1400 - 200$

   $4x = 1200$

   Finally, divide both sides by 4 to solve for (x:

   $x = 1200 / 4$

   $x = 300$

   So, the solution to this equation is also $x = 300$.

3. $7325 - 2x - 409 = 4178$

   First, combine like terms on the left side:

   $7325 - 409 - 2x = 4178$

   $6916 - 2x = 4178$

   Now, isolate $x$ by subtracting 6916 from both sides:

   $-2x = 4178 - 6916$

   $-2x = -2738$

   Finally, divide both sides by -2 to find (x:

   $x = -2738 / -2$

   $x = 1369$

   So, the solution to this equation is $x = 1369$.

4. $9907 - (8x + 325) = 4214$

   First, distribute the negative sign on the left side:

   $9907 - 8x - 325 = 4214$

   Next, combine like terms on the left side:

   $9907 - 325 - 8x = 4214$

   $9582 - 8x = 4214$

   Now, isolate $x$ by subtracting 9582 from both sides:

   $-8x = 4214 - 9582$

   $-8x = -5368$

   Finally, divide both sides by -8 to find (x:

   $x = -5368 / -8$

   $x = 671$

   So, the solution to this equation is $x = 671$.
